have inventedy a new and; useful Improvement; in Squeeze-Rolls forVVoolNashiiig` Machinery, of vvhicli the following yis aspeci` fication.

This invention. relates to squeeze-rolls for.

Woolfwashing. machinery and other` appara.- tus, andg it has for itsobject the provision of. a squeezc-rolly made .up ofl annular sectionsof vulcanized rubber'cornpound or other suitable material Whicharesecure'du ,on a, shaft or-axis upon supporting collars o suchconstruction that s Wholly obviatedwithout the employment of greatpressure in clamping. the roll sections to ether.

.nl the accompanying drawings I- have illustrated one embodiment of my`invention, but it is to be understood that variations in the details of,the construction; illustrated .may be resortedA to` Within, the scope ofthe 25,

appended. claims without departing fromy the spirit of,v the invention.

In the drawings, in which` correspondingv parts are designated. bysimilar 'charactersofV referenccthrougliout: Figure 1 isa pers Vec.-`

. tive4 View of a complete roll, constructef` in accordance with thepresent invention, a poi'- tion` ofI the roll being broken away' to showthe internal arrangement of the devices for securing the roll sectionsupon` the shaft. Fig. 2 is a face view of one of the supporting collarsyupon` which the roll sections are mounted. Fig. 3 is aface view of oneof the roll; sections, the recesses on the hidden` face ofthesectionbeing indicated inA dotted lines.

As illustrated, each roll comprises a shaft oiyaxis 1y of suitable(,liinensions which is preferably provided throughout a portion ofitsdeiigtlr vyitli a longitudinally disposed rib orl spline 2. Therollfsectibiisl, Which-vary innumber according toV thelength of the`r'oll desired, have annular bodies of a suitable rubber compound and areheld` upon the` shaft between end. lates l; which are ordi,- narilyof'soinewhat arger diameter than the roll; sections. Each of the rollsections 3 is secured upon and between two supporting collars 5 each ofwhich is internally notched at 6 to engage with the spline 2. on ,the4shaft.

Each of the collars 5 presents a beveled seat-r ippingr of the roll,sections is` t ing surface upon which the innermost sur, 'face oftheroll section carried by the col ar is., Seated, and at the distal edgeof the inelin di yseating surface 7 thereis a flange Whe s Patentedsept; 2 9. 1 908;`

vcorru ated on the face adjacent to` thefinl-l,`

eline seating surface and flat on the other, asbest shown in Fig. 1.. 4On the corrugated faceof the flan e 48 at intervalsof ninety'def greesare provi ed four lugs 9, as bestv shown; in Figs. 1 and-2, these lugsbeing. adaptedftoy engage` with. recesses formed therefor in th'elvfaces of the roll sections 3. The facesotthe. `roll sections are,furthermore, corrugatec'l-y ,near their inner peri heriesto conform totheI corrugations forme on the flanges 8, as.,v clearly shown in Figs. 1and 3. The recesses;

10 which are formed inthe faces of therolhY `sections to receive thelugs 9 are of consider? ,able depth and, in order to revent.y weaken:

ing the roll sections unduly y the formationI kof these recesses, tli/erecesses on onefawceoff'` i each` roll section are arranged: between,the recesses on the opposite face, as clearly shown in Fi 3.

In asseinling the elements of the rolt structure the` collars and roll`sections areQS fitted upon the shaft successively in the rela: tionshown in Fig. 1, then the assembled,y rollt sections and collars areforced together,

Ithe application of sufficient pressure to sure close contact of theroll sections and,y a;

lsufficient degree of compression ofthe ii'iatefr `rial of the rollsections to prevent separatio of the sectionsat the periphery oflthelroe when in service. Then the end. plates 4l are secured firmly uponthe shaft of the rolt-and; the structure is complete. i

` As willbe readily seen, the supportingcQle-.- lars upon which the rollsections are mounted` and between which the roll sections are posi;-vtively gripped are positively locked upontheL shaft so that no rotationon the Shaft is possible. The corrugated faces of the flanges 8y and tlieiugs 9 provided thereon ob taina iirm hold upon theroll sectionsA and,effectively prevent any distortion of the rolll sections4r on the shaftwhen in service. Moreoyer,

Iparts of the` roll are so designed that in case,

new sections introduced to replace those have been damaged.

Having thus described my. inyent-ion, what 199i and anycircumferentialmovement thereof rality of collars keyed to secure byLetters ising a shaft, a, pluthereon hav' i11- 5 clined seatin surfacesfor the roll-sections and outwar y-extending flanges adapted to engaeIt-he faces of'the'rollesections, and a plura. ity of roll-sectionssupported upon and between said collars and engagingy said in- 0 clinedseating surfaces,

the flanges on said collars having circumferentiallyfcorrugated facesfor engegement wi th recessed corrugaally-arranged lugs on said corrugetengaging the recesses 1n said corrugations, 15`

tions on said roll-sections and havin radie faces whereby saidroll-sections are gripped and locked against rotative movement upon saidcollars.

In Atestimony whereof, I have signed. my name in the presence of twowitnesses.
